Is the jump starter adequately charged? Are the battery terminals clean, without a coating of dirt, grease or the white powdery residue from a corroded terminal? Are the device’s clamps tightly secured on the terminals? Another common problem is that the car battery is too discharged for the device to recognize it.

The best gauge for determining which jump starter is right for your vehicle is its cranking or starting amps rating.
